Description
Starter 9625382780 D7R27 designed for diesel engines in Citroën and Peugeot vehicles with 2.0 and 2.2 HDi engines.
This Valeo starter (D7R27) is a direct-fit replacement for a range of Citroën and Peugeot 2.0 / 2.2 HDi diesel engines. It is frequently searched by part number (9625382780, D7R27 and related references) and is suitable for professional workshops and hands-on DIY mechanics who need a reliable swapping solution. The unit operates the engine during cranking by engaging the pinion with the flywheel and delivering the high torque needed to turn the diesel combustion engine, ensuring consistent cold starts and engine engagement under load.

How It Works
The starter converts electrical energy from the battery into mechanical rotation. When you turn the key or activate the starter relay, the solenoid pushes the pinion to engage the ring gear on the flywheel and supplies current to the motor armature. Once the engine fires and exceeds starter speed, the pinion disengages. Key subcomponents are the solenoid, pinion/Bendix drive, motor armature and brushes, and the starter housing with mounting flange.
Installation Recommendations
- Always disconnect the negative battery terminal before starting work to prevent short circuits and accidental cranking.
- Access the starter from under the vehicle or from the engine bay depending on model. Support the vehicle safely on stands or a lift when working underneath.
- Disconnect electrical connectors and remove mounting bolts. Support the starter as you remove the final fastener to avoid dropping it.
- Inspect the flywheel ring gear teeth for wear or damage and check the starter mounting faces for corrosion or distortion.
- Clean and inspect battery cables, the ground strap and connector contacts; replace any corroded or damaged wiring to ensure proper cranking current.
- Reinstall and tighten mounting bolts to the manufacturer’s torque specification, reconnect wiring and the battery, then perform a functional test by cranking the engine.
- If unsure, have installation performed or checked by a qualified technician with appropriate tools and lifting equipment.
Most Common Failure Reasons
- Worn Brushes Or Commutator Wear Causing Loss Of Electrical Contact.
- Solenoid Failure Or Faulty Starter Switch Preventing Engagement.
- Seized Or Worn Bendix/Freewheel That Fails To Engage Or Disengage Properly.
- Oil Contamination From Engine Leaks Causing Premature Wear Or Slippage.
- Corroded Or Poor Electrical Connections Resulting In Voltage Drop And Reduced Torque.
- Heat Damage Or Water Ingress In Vehicles Exposed To Harsh Conditions.
For best results, check battery health and charging system condition before replacing the starter—low battery voltage or a weak alternator can mimic starter faults. Replacing the starter together with addressing underlying electrical or oil-leak issues reduces the chance of repeat failures.
